I tried connecting to the VM manually with vinagre, and then vinagre
segfaulted as well. So it's a problem somewhere in the VNC library.
Note that the VM keeps running and libvirt seem fine. It's just the
virt-manager user interface launching a VNC viewer, or vinagre, ditto.
I installed debug symbols from libgtk-vnc-1.0-0-dbg and ran python in
gdb. Crashed somewhere else than where reporter titled bug.
(gdb) run /usr/share/virt-manager/virt-manager.py --debug
Program received signal SIGSEGV, Segmentation fault.

On a desktop running Maverick here; this is kinda blocking testing
upcoming releases.
